Titanium was found at six times reporting limits in Oregon snow, while iron was three times over.

Snow collected December 27, 2016, in Chiloqion OR, contained 3.1μg/L of titanium, more than six times the reporting limit of 0.5μg/L. Iron clocked in at 59μg/L (RL 20μg/L) and aluminum at 88μg/L (RL 50μg/L). Barium & strontium were below reporting limits. (Apologies for the typo on the report – while McCampbell received the sample January 2017, I mistakenly wrote December 2017 on the form.)
